Traveling with a Continuous Glucose Monitor (CGM) can feel daunting, especially for first-time travelers who rely on this life-changing technology to manage diabetes. Questions about whether CGMs can safely pass through airport security and how to protect these devices during travel are common. In this article, we’ll explore everything you need to know about traveling with a CGM, focusing on the crucial question: Can CGM go through airport security safely?
Understanding CGMs and Their Importance
CGMs are small, wearable devices that continuously monitor glucose levels in real time. They use a tiny sensor placed under the skin to measure glucose levels and send data to a receiver or smartphone app. For people with diabetes, CGMs provide critical insights that help maintain stable blood sugar levels, making them indispensable tools.
When traveling, especially by air, it’s natural to worry about how security procedures, such as X-ray machines and body scanners, might affect the functionality of your CGM. Rest assured, with the right knowledge and preparation, you can travel with your CGM confidently and safely.
Can CGM Go Through Airport Security?
The short answer is yes—but with some caveats. CGMs can go through airport security, but travelers must take precautions to avoid exposing their devices to potentially harmful conditions. Here’s a breakdown of the key considerations:
1. X-Ray Machines
X-ray machines are commonly used to screen carry-on luggage. While most CGM manufacturers, including Dexcom, Abbott (Freestyle Libre), and Medtronic, state that their devices are designed to withstand low levels of radiation, they typically advise against putting CGMs or their components (such as transmitters and receivers) through X-ray scanners. Prolonged or repeated exposure to X-rays might damage the device or affect its accuracy.
2. Body Scanners
Full-body scanners use millimeter-wave technology or backscatter X-rays. Most CGM manufacturers recommend avoiding backscatter X-rays, as they could interfere with your device. Millimeter-wave scanners, on the other hand, are generally considered safe. If you’re unsure about the type of scanner in use, always err on the side of caution.
3. Handheld Metal Detectors
Handheld metal detectors are commonly used for security screening. While these devices pose less risk than X-rays, prolonged exposure could still potentially affect the CGM. If a handheld detector is used, request that the officer avoid scanning directly over the CGM sensor or transmitter.
Tips for Navigating Airport Security with a CGM
Proper planning and communication are essential for a smooth security screening experience. Follow these steps to protect your CGM and make the process as stress-free as possible:
1. Inform the TSA Agents
As you approach the security checkpoint, inform the TSA agents that you’re wearing a CGM. Let them know that your device should not be exposed to X-rays or certain types of scanners. Showing them a manufacturer’s note or medical device card can help clarify your request.
2. Request a Manual Inspection
If you’re concerned about the potential risks of X-ray machines or body scanners, request a manual inspection. TSA agents are trained to handle medical devices and will accommodate reasonable requests. Keep in mind that this process may take a few extra minutes, so plan accordingly.
3. Carry Documentation
Bring a letter from your healthcare provider explaining your need for a CGM and any associated supplies. Some manufacturers also provide medical device cards that outline the specific precautions for airport security. Having these documents on hand can prevent misunderstandings.
4. Keep Spare Supplies in Your Carry-On
Always pack extra sensors, transmitters, and batteries in your carry-on luggage. If your CGM malfunctions due to security screening or other travel mishaps, you’ll have replacements ready. Keep these items in a separate, clearly labeled bag to facilitate inspections.
5. Know Your Rights
The Transportation Security Administration (TSA) allows travelers with medical devices to request alternative screening methods. If you feel uncomfortable with the standard screening procedures, you can assert your right to a manual inspection or opt-out screening.
Manufacturer Guidelines for CGMs and Airport Security
Let’s take a closer look at the specific guidelines provided by some of the leading CGM manufacturers:
Dexcom
Dexcom recommends avoiding X-ray scanners and backscatter body scanners. Instead, they advise requesting a manual inspection for both the sensor and the receiver. Their devices are generally safe to pass through millimeter-wave scanners.
Freestyle Libre (Abbott)
Freestyle Libre sensors and readers are not designed to withstand X-rays. Abbott advises users to request a manual inspection and avoid passing the device through luggage scanners. Millimeter-wave body scanners are generally safe.
Traveling Internationally with a CGM
When traveling internationally, additional considerations may apply. Here’s what you need to know:
1. Research Local Regulations
Airport security protocols vary by country. Research the security procedures at your destination to ensure compliance and avoid unnecessary complications.
2. Language Barriers
If you’re traveling to a country where English is not widely spoken, consider bringing translated documentation that explains your medical needs. This can help smooth the process at security checkpoints.
3. Time Zone Adjustments
Adjusting your CGM’s settings to reflect the new time zone can help ensure accurate data tracking. Plan for this in advance to minimize disruption to your diabetes management routine.
Tips for Smooth Air Travel with Diabetes
In addition to navigating airport security, managing diabetes while flying requires extra preparation. Here are some helpful tips:
1. Pack Smart
Bring all necessary diabetes supplies, including insulin, CGM accessories, and snacks, in your carry-on bag. Airplane cabins can be unpredictable, so it’s essential to have everything you need within reach.
2. Stay Hydrated
Air travel can be dehydrating, which may affect your glucose levels. Drink plenty of water to stay hydrated throughout your journey.
3. Monitor Your Glucose Levels
Flying can cause stress and changes in activity levels, which might impact your blood sugar. Keep a close eye on your glucose levels during the flight and be prepared to make adjustments as needed.
4. Plan for Delays
Flight delays are always a possibility. Pack enough supplies to cover unexpected changes to your travel plans, and keep snacks or glucose tablets on hand for quick adjustments.
Frequently Asked Questions
Can I wear my CGM sensor during the flight?
Yes, you can wear your CGM sensor during the flight. The device will continue to function as usual.
What should I do if my CGM malfunctions after security screening?
If your CGM malfunctions, use your backup supplies to replace the damaged sensor or transmitter. Contact the manufacturer’s support team for further assistance.
Are insulin pumps and CGMs treated the same at airport security?
While insulin pumps and CGMs are both medical devices, they may have different manufacturer guidelines. Always check the specific recommendations for your device before traveling.
Can I bring liquid glucose or juice through security?
TSA allows passengers with diabetes to bring medically necessary liquids, including glucose treatments, through security checkpoints. Inform the agents and place these items in a separate bag for inspection.
What should I do if TSA agents are unfamiliar with CGMs and deny alternative screening?
Politely explain your CGM is a medical device that can’t go through X-rays or backscatter scanners. Show your doctor’s letter or device card for clarification. If needed, ask for a supervisor or a TSA Passenger Support Specialist (PSS). Calling TSA Cares ahead of your trip can also help arrange assistance.
Conclusion
So, can CGM go through airport security safely? The answer is yes, but with precautions. Understanding your device’s specific guidelines, communicating with TSA agents, and being prepared for alternative screening methods will help ensure a smooth and stress-free travel experience.
With proper planning, you can focus on enjoying your journey instead of worrying about your CGM. Safe travels!
